Abstract

A method of manipulating and obtaining access to graphical desktop objects is disclosed. Touch-sensitive fields are provided on a computer display for user selection. Upon selecting one of the fields with a fingertip, a fingerprint therefrom is analyzed and compared to a list of authorized fingerprints. Once the fingerprint passes inspection, the user is granted access to the underlying program.

Claims

1. A method of manipulating data availability on a data processing system in order to allow general availability of the data processing system to a plurality of authorized users while allowing access to specific data thereon only to predetermined members of a subset of the authorized users, the subset being less than the whole of the authorized users, comprising the steps of:

storing in an access table on the data processing system a representation of a master fingerprint of each of the authorized users, said representation matched to a list of what specific data to which each of the authorized users are to be granted access;

one of the authorized users selecting a touch screen field, said field representing at least one portion of said specific data and said field being displayed on a monitor interconnected to the data processing system, by touching said field with a finger of said one of the authorized users;

obtaining a current fingerprint from said one user'"'"'s finger on said touch screen field during said step of selecting a touch screen field;

comparing said current fingerprint with each said representation in said access table; and

granting access to said at least one portion of said specific data if said one user'"'"'s current fingerprint from said step of obtaining matches with one said representation in said access table and if said at least one portion of said specific data is on said list for said one of the authorized users.

2. The method of claim 1, wherein said step of selecting a field comprises:

selecting a graphical object.

3. The method of claim 1, wherein said step of selecting a field comprises:

selecting a textual field.

4. A system for manipulating data availability on a data processing system in order to allow general availability of the data processing system to a plurality of authorized users while allowing access to specific items of data thereon only to predetermined members of a subset of the authorized users, the subset being less than the whole of the authorized users, comprising:

means for storing in an access table on the data processing system a representation of a master fingerprint of each of the authorized users, said representation matched to a list of what specific data to which each of the authorized users are to be granted access;

means for allowing one of the authorized users to select a touch screen field, said field representing at least one portion of said specific data and said field being displayed on a monitor interconnected to the data processing system, by touching said field with a finger of said one of the authorized users;

means for obtaining a current fingerprint from said one user'"'"'s finger on said touch screen field while selecting said touch screen field;

means for comparing said current fingerprint with each said representation in said access table; and

means for granting access to said at least one portion of said specific data if said one user'"'"'s current fingerprint, obtained while selecting said touch screen field, matches with one said representation in said access table and if said at least one portion of said specific data is on said list for said one of the authorized users.

5. The system of claim 4, wherein said means for allowing one of the authorized users to select a touch screen field comprises:

means for allowing one of the authorized users to select a graphical object.

6. The system of claim 4, wherein said means for allowing one of the authorized users to select a touch screen field comprises:

means for allowing one of the authorized users to select a textual field.
